I followed these instructions and it all worked out fine (left out the
examples directory of U boot though) , but after the reboot in lowboot
jumper configuration, i only see garbage on my minicom screen. I can
figure out some characters that look familiar (like the countdown for
the autostart) so I assume it's working correctly but doesn't get
displayed right. I also can't interrupt the countdown so input doesn't
work. Already tried to change the 115200 8N1 settings of the
communications (but why would they change anyway..) and didn't help.

What could possibly be wrong ??

checked it and there's a resistor between 2-3 and not 1-3 so i guess
that's right.. (I have version 2.0 Lite)
